The marked price and cost price of a book are Rs 850 and Rs 748 respectively. The discount in percentage is?
(a) 12%
(b)10%
(c)15%
(d)8%
To find the discount percentage, you can use the formula:
\[ \text{Discount Percentage} = \left( \frac{\text{Marked Price} – \text{Cost Price}}{\text{Marked Price}} \right) \times 100\]
Given that the marked price (\(MP\)) is Rs 850 and the cost price (\(CP\)) is Rs 748:
\[ \text{Discount Percentage} = \left( \frac{850 – 748}{850} \right) \times 100 \]
\[ \text{Discount Percentage} = \left( \frac{102}{850} \right) \times 100 \]
\[ \text{Discount Percentage} \approx 12\% \]
Therefore, the discount percentage is approximately 12%.
